Benefits of technology
This solution ensures an even circumference of the dielectric layer, enhancing the sealability and reducing manufacturing costs by eliminating the need for additional steps in forming aid members, thereby improving the overall quality and reliability of the PDP.
Problems solved by technology
The wavy circumference of the dielectric layer lowers a sealability of a seal member, leading to degradation in quality of a PDP.
Accordingly, the wavy circumference of the dielectric layer 215 causes the disadvantages shown in FIGS. 17B and 17C, resulting in occurrence of the malfunctions such as the sealing leak and the abnormal discharge.
This unevenness causes a variation of gaps in the PDP, resulting in degradation in quality of the PDP.
However, the configuration of the conventional PDP, for example, the PDP disclosed in Patent Document 1 fails to suppress the waviness width at the circumference of the dielectric layer and accordingly fails to avoid the respective malfunctions.

embodiments
[0078]With reference to FIG. 1, description will be given of a basic configuration of a PDP 100 including a front plate for PDP according to one embodiment of the present invention (hereinafter, referred to as a front plate 1). FIG. 1 is a perspective view schematically showing a basic structure of the PDP 100 including the front plate 1 according to the embodiment of the present invention. The basic structure of the PDP 100 in this embodiment is similar to that of a typical PDP of an AC surface discharge type.
[0079]As shown in FIG. 1, the PDP 100 includes the front plate 1 and a back plate 2 arranged so as to face the front plate 1. Herein, an outer periphery between the front plate 1 and the back plate 2 is surrounded with a seal member 18 (see FIG. 3) such as glass frit. That is, the PDP 100 is sealed hermetically with the seal member 18, so that a discharge space 30 is formed inside the PDP 100. The discharge space 30 is filled with a discharge gas containing neon (Ne), xenon (X...

In a front plate for PDP, which includes: a large number of display electrodes formed in stripes on a substrate; a plurality of terminal groups for connection with an external drive circuit, each terminal group being formed along an edge of the substrate, the edge being extended in a direction orthogonal to an extending direction of the display electrode; and a large number of lead electrodes extended from the display electrodes, respectively, in a non-image display region on the substrate to gather toward any one of the terminal groups without intersecting each other, the lead electrodes being connected to corresponding terminals in the relevant terminal group, respectively, further, a large number of strip-shaped aid members for aiding formation of a dielectric layer are formed in a region located between the adjacent terminal groups. Thus, it is possible to make a circumference of a dielectric layer even although a dielectric material to be used is low in viscosity.
Description
TECHNICAL FIELD[0001]The present invention relates to a plasma display panel for use in an image display device and the like. More specifically, the present invention relates to a configuration and a manufacturing method of a non-image display region on an outer periphery of a front plate of the plasma display panel.BACKGROUND ART[0002]A plasma display panel (hereinafter, referred to as a PDP) allows realization of a high degree of definition and a large screen, and therefore is for use in a large television set having a screen size of, for example, 65 inches or more. Recently, such a PDP has been applied increasingly to a high-definition television set having scanning lines the number of which is more than twice as large as those of a conventionally known television set adopting an NTSC system, and further reduction in cost thereof has been demanded.[0003]A PDP basically includes a front plate and a back plate. The front plate typically includes a front substrate, a large number of...
